Description

BoBoCoAe, 2014, 286 pages, ISBN: 8740307530 9788740307535This book is Part III of the series on Applied Thermodynamics: Software Solutions, and contains three chapters, viz. Refrigeration cycles, Air compressors and Thermodynamic relations.Under ‘Refrigeration cycles’, following cycles are analyzed: Ideal and actual vapour compression cycle, Ideal and actual reversed Brayton cycle (or, Bell Coleman cycle). Several useful Mathcad Functions are written for properties of Refrigerant- R134a in superheated and two-phase regions, which are used in solving problems. Also, useful Mathcad Functions are written to facilitate easy calculations for all these cycles. And, many useful Functions/Procedures are written in EES for different variations of ideal vapor compression refrigeration cycle.Under ‘Air compressors’, reciprocating air compressors (both single stage and multi-stage) are analyzed. Formulas to calculate various parameters such as: volumetric efficiency, work required for actual compression, isothermal efficiency, minimum work required for two- stage (or multistage) compression with perfect inter-cooling etc. are presented.Under ‘Thermodynamic relations’, relations are presented to calculate ‘Thermodynamic properties’ which are impossible or difficult to measure (such as: entropy, internal energy, enthalpy, Helmholtz function and Gibbs function), in terms of measurable quantities such as pressure, volume and temperature.In these chapters, problems from University question papers and standard Text books are solved with Mathcad, EES and TEST.Content Refrigeration Cycles Definitions, Statements and Formulas used[1-7] Problems solved with Mathcad Problems solved with DUPREX (free software from DUPONT) [8] Problems solved with EES Problems solved with TEST ReferencesAir compressors Definitions, Statements and Formulas used[1-6] Problems solved with Mathcad Problems solved with EES ReferencesThermodynamic relations Summary of Thermodynamic relations [1–6] Problems solved with Mathcad Problems solved with EES Problems solved with TEST References
